FIX: Asus Computer Boots Into Aptio Setup Utility Instead of Booting Into its OS

The Aptio Setup Utility can sometimes open automatically on an ASUS laptop instead of starting Windows. This usually happens after a forced shutdown, a system crash, or when some BIOS settings have changed. When you see this screen, it means your laptop cannot find the hard drive or the Windows system it needs to start up.

The most common reason is that the storage device is missing or not connected properly. However, this problem can also happen if certain BIOS settings are not right, such as if CSM is turned off, Secure Boot is set up incorrectly, or the order of boot devices has changed.

In this article, we will discuss different ways to solve this error.

1. Make Sure that Your HDD/SSD is Properly Connected

The most common cause of this issue is a loose connection between your computer and its HDD/SSD, which can prevent your computer from detecting the drive.

1. Open your computer to access its HDD/SSD. If you have a desktop, open the case. If you have a laptop, carefully unscrew and remove the bottom panel.
2. Find the drive and gently unplug its connection from the motherboard.
3. Clean both the drive’s connector and the port on the motherboard to make sure there is no dust or debris.
4. Firmly reconnect the drive to the motherboard, ensuring it is seated properly.
5. Close up your computer.

Now, restart your computer and check if it boots normally.

2. Allow your computer to Recognize all HDDs and SSDs

If your HDD/SSD is properly connected but your computer still will not boot, it may be set to only recognize the original drive from the factory. In this case, you can adjust some settings in the Aptio Setup Utility to allow your computer to detect any HDD or SSD. Here’s how:

1. Turn on your computer. It should boot into the Aptio Setup Utility automatically.
2. Inside the Aptio Setup Utility, go to the Security tab.
3. Expand the Secure Boot menu and disable Secure Boot.
4. Go to the Save & Exit tab, save your changes, exit the Aptio Setup Utility, and restart your computer. You should return to the Aptio Setup Utility after restarting.
5. Go to the Boot tab.
6. Disable Secure Boot and Fast Boot, if they are enabled.
7. Enable CSM (Compatibility Support Module).
8. Return to the Save & Exit tab, save your changes, and exit.

Restart your computer once more. When your computer boots, it should now load your Operating System instead of the Aptio Setup Utility.
